4 Claims.4 (Cl. 2515-130) This invention relates -'to calculating machines, and more particularly to 'a calculating machine having a mechanism embodied therein generally termed an enforced designation mechanism,A

l to depress a key in each of the three' columns before the machine could be operated.

It is the purpose of this invention to provide a v construction whichA increases the flexibility and adaptability of the machine, particularly as to the enforced designation" mechanism.

More specically, it is the purpose of this invention tol provide a commotion whereby certain designation keys may be grouped, each of which groups may contain one or more banks of keys, each bank comprising one or more individual keys, and so arranged that it is only iecessary to depress any one key oi the group instead of every key in the group to release the enforced designation mechanism and whereby the enforced designation mechanism may be controlled by and/or partially or totally disabled by certain control keys. Other novel features and resultant advantages will'be apparent, to those skilled in the art, from a consideration of the following description of one embodiment of this invention given in connection with drawings, in which.-

The -invention is illustrated as being applied to a "Burroughs portable calculating vmachine combined with a cash drawer of the type disclosed in the Horton Patent No. 1,853,050 and in my prior application, Serial No. 503.690, filed December 30, 1930.

The `construction of the calculating machine is well known and accordingly will ybe described only briefly, it being understood that the inven- 5 tion, although particularly useful in connection with cash drawer type machines, can also be applied to machines of other makes and types.

Calculating machine in general 10 In the illustrated form of thisinvention, the machine is provided with: a bank of control keys I, three banks of amount keys 2, and four banks of designation keys 3, the 4th, 5th, and 6th -banks of keys being coupled together as a group and l5 the '7th bank being a single bank or group. The

control keys include the total key, subtotal key, error key, non-add key, and other keys not shown. The amount keys control the forward movement of differential stop bars 4 connected to 20 actuator racks 6 with which one or more registers 1 are adapted to cooperate. The actuator racks 3 also control suitable printing mecha.-` nisms including type bars 3 and hammers 0 which cooperate to print upon a roll of paper Il 25 traveling around a platen I2.

`The calculating machine is mounted upon a cash drawer housing I3 which contains a cash drawer, the latter being controlled by the suitable and desirable control keys as shown and described 30 in the aboveapplication, Serial No. 503,690.

The illustrated machine is a hand-operated machine although it could be operated by a motor as shown in the heretofore mentioned Horton patent. In the illustrated hand operated 35 machine the operating handle 2| is utilized to oscillate the main shaft 22 to which is secured a dog. 23 which, upon the forward stroke of the machine engages a pivoted pawl or hookv24 carried by the full stroke sector 25 to which is 40 drivingly secured the driving plate 28 (Fis. 4)

` which operates certain portions of the calculating mechanism. A pivoted latching dog 21 is provided for' disabling hook 24 if the machine has not been'properly conditioned for use. The 45 dog 23, hook 24 and latch 21 constitute a disconnectible connection between the driving shaft and the machine proper which disconnectible means is utilized to enforce depression of one or more designation keys. In normal operation of 50 the machine, i. e., when properly conditioned, a stud or pin 23 carried by one arm of a crank 2Q moves up into a cam slot 30 formed in latch 21 to withdraw the latch from operative engagement with hook 24 to `permit full operation of 55,

the operating mechanisms. For additional details as to the construction of the calculating machine, reference is made to the heretofore mentioned Horton patent.

Enlorced designation released by any key in a group of banks In some classes of work such, for example, as oil station work, it is desirable not only to have the clerk or attendant depress a key in a bank of keys indicating what has been sold, but also to force him to record the quantity in gallons or I Y made for accomplishing this result as follows:

A detent in the form of a bell crank Il has one arm 3,2 movable into position to engage latch 21 to prevent its movement out of its hook engaging position in which it engages hook 24. Bell crank ll is controlled by one or more designation keys of a plurality of banks of keys and for this reason has an upwardly extending arm Il bifurcated to receive a downwardly projecting lug ll of a bail Il extending across the forward end of the machine and pivoted upon a shaft 31. Bail II is also provided with a vseries of upwardly extending lugs or fingers 3l which extend up and behind the hooked forward ends of slides Il, there being one lug and one slide for each bank of designation keys. Slides 3l extend through slots in designation keys Il formerly occupied by keyboard spacing plates common to this type of machine. The slides l! are urged rearwardly by the springs Il (Figs. 1 and 4) when the key locking slides 35 (Fig. 2) re- .lease the keys -for rearward movement. Bail 36 is urged in a counterclockwise direction (Figs. 3, 4 and 5) by a spring Il which urges lugs 38 into engagement with the hooked ends of the slides Il.

In the illustrated embodiment of this invention, the left bank of designation keys is employed as an independent bank whereas the three adjoining banks are coupled together as a single group. For this purpose, the three slides 39 of the 2nd, 3rd and 4th banks from the left are connected together by a rod I3 whereby depression of any one key in any of the three key banks associated with the three connected slides moves all of the slides. Bail Il, however, will not be released unless a key is depressed in the outer single designation bank at the same time a key is depressed in one of its inner three coupled designation key banks. In other words, there is a group control for three banks of designation keys and an independent control of one bank, although any key in the single bank will. of course, move its associated slide 39.

In certain uses of the machine it may not be desirable to have enforced or compulsory depression of keys in all the groups of designation keys. In other words, it may be desirable to disable the enforced designation mechanism associated with one or more groups of designation keys. The present invention provides for such a contingency by providing means for partially disabling the enforced designation mechanism as to certain keyspi. e., disabling one or more of the groups such as the group comprising the three coupled banks of designation keys.

Partial disablement of enforced designation by subtraction conditioning means In connection with an enforced designation machine such as just described, it is sometimes desirable to make entries where the only record that is wanted. besides the amount of the entry. is a record of the clerk who conducted the transaction. For example, if a quantity of money is paid out, the desired record is a record of the particular clerk who paid out the money and theamount of the transaction, which transaction should be a subtract operation. This kind of an operation should be possible without re quiring depression of all the different kinds of designation keys. Provision has accordingly been made for disabling part of the enforced designation feature by means of the subtraction conditioning means, while leaving other parts operative.

For this purpose the add subtract lever u is provided with a pin 46 which engages a cam arm 41 of a bail Il pivoted upon shaft 31 which bail extends partially across the front of the machine and terminates in a side arm ll also pivoted on the shaftl and extending upwardly and behind coupling rod I3 whereby rocking of bail Il will withdraw the three connected slides It, thus disabling the enforced designating effect of all three banks of designation keys and leaving only the outer slide l! in engagement with bail 36 and in enforced designation control of the machine.

Partial dsable'ment of enforced desanatonvby control key 'I'here are also transactions that are not "paid out transactions which require only a record of the clerk and the amount of the transaction. For example, it may be desired toopen the cash drawer by means of the no sale" key. In such event, all that is wanted is a record of the clerk who opened the cash drawer and it is therefore not desired to depress all the enforced designation keys. Provision has been made to accomplish this result as follows:

In the present instance an operation control key 50 is utilized which also disables the coupled three designation banks. For this purpose, slide 5| is utilized which extends through a slot in control key 50 and is provided with a cam shoulder 52 arranged to be engaged by the cross bar of the slot in control key 5l whereby depression of the key will move slide li forwardly. The forward end of slide ilV terminates in an abutment 53 positioned to engage a lug Il on bail I8 whereby a forward movement of slide. 5l will rock bail 48 counterclockwise and disable the three slides 39 that are coupled in one group.

Complete disablement of enforced designation by a key controlled lock` nisms, that is, both sets or groups of designation keys, from enforced depression, a normalizing lock (Fig. 3) operated by a sc -called managers key 55 is provided, which, when inserted in the lock and turned, moves a\ slide 56 rearward, thereby causing an upstanding projection of the slide to engage an offset lug 51 of a slide 58 and move said slide 58 rearward, thereby causing the lug 59 through an extension 60 to rock bail 36 counterclockwise to pull all four slides 39 forward to disable all groups of designation keys from enforced depression.. The machine is thus normalized as to all banks of keys to the right of the banks of designation keys. 'I'he tension of thev springs 40 when returning the slides 39 and 5I rearward is sufficient to overcome the tension of the spring 4I, consequently counterclockwise rotation of the bail 36 will restore the slide 58 to its normal position when key 55 is removed.

By the use of key 55 an authorized person may disable all the enforced designation mechanisms so that he can use the normalized portion of` the machine for checking or other purposes without his having to depress designation keys with every item he enters.'

Enforced designation by certain control keys and disablement of enforced designation by other control keys Under certain circumstances it is desirable to disable the entire enforced designation feature by means of vsome of the control keys which condition the machine to perform certain functions and to have other control keys form a part of the enforced designation feature. For example, a duplex register machine may be provided with a total key T (Fig. 4) for taking a. total from the detail register; a grand total key GT for taking a total from the lgrand total register; a no sale key 6I; -a cash key 62; a recd acct key 63; and a change 'key 64. This machine maytheri have a bank of enforced designation keys for enforcing registration of the kind of article sold and a group of banks for enforcing registration of the quantity sold. When the no sal. `ke 6| is depressed, or when the recd acctckey63 is depressed it is not desired to enforce registration of the kind of article or the quantity as no kind or quantity are involved in such a transaction.

Likewise when a total or a` grand total are taken it is not desired to enforce registration of kind of article or quantity. On the other hand, both change and cash sales should be recorded as such and the operator should be forced to depress the right key.

Where the enforced depression of designation keys is to be placed under control of certain of the operation control keys and other of the operation control keys are to be utilized to disable the entire enforced designation feature ofthe machine, a slide 65 passes through slots in all of the operation control keys and in the illustrated form is provided with four cams 66 positioned to be engaged by keys GT, T, 62 and 64 to move the slide forwardly. The forward end of slide 65 terminates in a hook adapted to engage a lug 38a similar to the lug 38 upon a bail 36. As in the case of the slides 39, slide 65 retains bail 36 against counterclockwise movement until slide 65 is moved forwardly by operation of either of the keys GT, T, 62 and 64,.

Upon depression of one of these four'keys, slide'I 65 is moved forwardly and it releases bail 36 .from its control, although bail 36 still remains under control of the other enforced designation keys and slides, which enforced designation keys must be depressed as formerly before the machines can be operated.

Provision is made whereby depression of either key 63 or 6I will disable the entire enforced designation mechanisms. For this purpose, a lever 61 pivoted at 68 is disposed beneath key 6I and is rocked clockwise I key 6I to cause the rear cam edge 69 of the lever to engage a stud 16 carried by a lever 1I. Stud 16 engages a tail 12 of a slide 13 and moves the latter rearward on its slotted connection with shaft 31 to cause a downwardly projecting finger 14 on slide ,13 to engage arm 68 of bail 36 to rock the latter counterclockwise to disable the entire enforced designation feature aspreviously described.

Depression of key 63 performs the same function by engagement of pivoted arm 15 connected to a link 16 which carriers a pin 11 which also engages the tail 12 and thus moves bail 36 counterclockwise in the'manner previously described to disable the enforced designation feature. Thus depression of keys 6I or 63 disables detent 32 by rrocking it out of the path of the latch 21 and permits operation of the machine without depression of any designation key.

Complete disablement of enforced designation by a control key upon depression of A modified form of construction for completely disabling the enforced designation feature by meansA of a control key is shown in Fig. 5. A slide 80 which takes the place of slide V5I of Fig. 3 passes through the slotted portion of the key 50, has a cam shoulder 8| which is engaged by the cross bar in the slot of key 50 to cam the slide 80 forward when key 58 is depressed and' terminates in a hooked forward end 82. A lug 83 similar to the lugs 38 extends upward from the bail 36 and engages hook Ashaped end 82 of `slide 80. The front portion of the hook 82 engages thefront face of the lug 83 and a nose 84 projecting from the lower forward end of slide 80 engages the rear face of the lug 82, so

that when the control key 50 is depressed to move slide 80 forward, nose 84 engaging the rear face of lug 93 will rock bail 36 counterclockwise and through the medium of the four lugs 38 will pull the slides 39 forward to disable all of the enforced'designation mechanisms as previously described in connection with the lock keys 55. Slides 80 and 39 wilLbe restored rearward by the springs 40, thereby restoring bail 36 clockwise against the tension of- 5spring 4I.

From the foregoing description, it will be apparent that there has been provided a calculating machine embodying a plurality of banks of designation keys, certain banks of which are combined into a group and are controlled by any lone key within the group, and that one or more groupsv can be disabledv by operation of certain `other keys such as operation control keys or a conditioning key such as the subtract lever, or that the entire designation means can be disabled by operation of one or more keys or other devices and that certain control keys may be constructed to be part of the enforced designation mechanism `whereas others disable all or part of the. enforced designation mechanism.

It will be apparent to those skilled in the art that minor changes may be made'in details of the construction without -departing from the spirit and scope of this invention as deilned in the appended claims.

I claim:

1. A calculating machine having a plurality saidV keys required to be depressed to permit operation of said machine without depression o! said keys.

3. A calculating machine having a plurality of banks of depressible keys including designation keys, operation control keys, and amount keys, means for operating said machine, and mechaoperation control keys for disabling all of said mechanisms.
